EMB-190 Captain reported the loss of #2 Hydraulic System after landing required a tow to the gate due to no nose wheel steering.

Narrative

We had a normal landing on Runway XX at ZZZZ. On the landing rollout I applied the brakes and slowed to taxi speed. A 180 degree turn on the runway is required due to no parallel taxiways. While executing the turn we received a FLT CTRL NO DISPATCH; EICAS (Engine Indicating and Crew Alerting System) message. As we continued the taxi on the runway a HYD 2 LO PRESS; EICAS message presented. Shortly thereafter while exiting the runway onto Taxiway 1; I lost nose wheel steering but was able to continue the turn with the pedals and differential braking. STEER FAIL; EICAS message also presented at this time. I stopped the aircraft on Taxiway 1 and set the parking brake. We followed the HYD 2 LO PRESS QRH procedure. A view of the hydraulic synoptic page confirmed that we had lost all fluid and pressure from the Number 2 system. We advised ATC that we'd need to be towed to the gate / hardstand due to our abnormal; and that there was likely hydraulic fluid on the runway. MX (Maintenance) and Dispatch were notified and a logbook entry was made.
